These days I often use launchpadlib in my projects for scripting access/modifications in Launchpad. While launchpadlib has quite a good API documentation, this only covers the method calls, not the attributes or collections. So it often takes some poking and trying until you figure out how to access/change things.

I found myself typing the same things over and over, so I finally wrote a little script called lpshell:

#!/usr/bin/python -i
import code, os, sys
from launchpadlib.launchpad import Launchpad, STAGING_SERVICE_ROOT, EDGE_SERVICE_ROOT
lp = Launchpad.login_with('test', STAGING_SERVICE_ROOT)

This logs into Launchpad and gives you an interactive Python shell with an “lp” object:

$ lpshell
>> lp.bugs[439482].duplicate_of
<bug at https://api.staging.launchpad.net/beta/bugs/432598>

Update: I committed this to ubuntu-dev-tools now, renamed to lp-shell for consistency with the other lp-* commands.
